Abstract
The invention discloses a humeral greater tuberosity compression locking steel plate which comprises a steel plate body and screws. The steel plate body is a triangular steel plate without closed angles. The steel plate body is arc-shaped. Three screw holes are formed in the surface of the steel plate body. The screws are vertically mounted on the surface of the steel plate body. Three kirschner wire fixing holes are formed in the middle of the steel plate. Rotator cuff sewing holes are designed at the edge of the steel plate body. The humeral greater tuberosity compression locking steel plate has the advantages that the steel plate is made into a spherical surface conforming to humeral head anatomy to increase containment and compression of the steel plate to fractured bone blocks or crushed bone blocks, the screws are fixed with the steel plate in an angled manner to increase vertical pulling out force resistance, the steel plate is designed into the size only fixing a humeral greater tuberosity to facilitate minimally invasive operations, and the problem that the crushed fractured bone blocks cannot be fixed by the screws is solved.
Description
Technical field
The invention belongs to medical instruments field, relate in particular to a kind of greater tubercles of humerus locking and pressurizing steel plate.
Background technology
There is no at present special steel plate for fracture of greater tuberosity of the humerus, only have hollow screw to fix, the constant intensity of screw is smashed sclerite not and easily, makes to be screwed to require fracture of greater tuberosity of the humerus piece enough greatly, if sclerite is pulverized, can not fix.
Summary of the invention
The object of the present invention is to provide a kind of greater tubercles of humerus locking and pressurizing steel plate, be intended to solve that to make to be screwed fracture of greater tuberosity of the humerus requirement fracture of greater tuberosity of the humerus piece must be enough large, if sclerite pulverizing, problem that could not be fixing.
The present invention realizes like this, a kind of greater tubercles of humerus locking and pressurizing steel plate comprises steel plate and screw, described steel plate is without wedge angle triangle steel plate, steel plate is arc shape, surface of steel plate is provided with three screw holes, screw is installed perpendicular to surface of steel plate, is provided with three Kirschner wire fixing holes in the centre position of steel plate, has shoulder sleeve sewing hole in steel plate edge designs.Further, the angle between described every two screws is 10 degree.
Further, the angle between the axis of described screw hole and surface of steel plate centrage is 30 degree.
Further, the size of described greater tubercles of humerus locking and pressurizing steel plate only can be fixed greater tubercles of humerus.
Further, the fixing employing lock-in techniques between described steel plate and screw.
Effect gathers
Greater tubercles of humerus locking and pressurizing steel plate of the present invention is made into sphere and meets head of humerus dissection, increase containing and the compressing of steel plate to sclerite or pulverizing bone piece, screw and steel plate are angled fixing, increase anti-vertical withdrawal force, steel plate design becomes only to fix trochiterian size, be conducive to Micro-operation, solved sclerite pulverizing and can not make the problem being screwed.
Accompanying drawing explanation
Fig. 1 is the top view of the greater tubercles of humerus locking and pressurizing steel plate that provides of the embodiment of the present invention;
Fig. 2 is the front view of the greater tubercles of humerus locking and pressurizing steel plate that provides of the embodiment of the present invention;
In figure: 1, steel plate; 2, screw hole; 3, Kirschner wire fixing hole; 4, shoulder sleeve sewing hole; 5, screw.
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 and Fig. 2 show the structure of greater tubercles of humerus locking and pressurizing steel plate of the present invention, as shown in the figure, the present invention is achieved in that a kind of greater tubercles of humerus locking and pressurizing steel plate comprises steel plate 1 and screw 5, and described steel plate 1 is without wedge angle triangle steel plate, steel plate 1 is arc shape, steel plate 1 surface is provided with three screw holes 2, and screw 5 is installed perpendicular to steel plate 1 surface, be provided with three Kirschner wire fixing holes 3 in the centre position of steel plate 1, have shoulder sleeve sewing hole 4 in steel plate 1 edge designs.
Further, the angle between described every two screws 5 is 10 degree.
Further, the size of described greater tubercles of humerus locking and pressurizing steel plate only can be fixed greater tubercles of humerus.
Further, the angle between the axis of described screw hole and surface of steel plate centrage is 30 degree.
Further, the fixing employing lock-in techniques between described steel plate 1 and screw 5.
Greater tubercles of humerus locking and pressurizing steel plate of the present invention is made into sphere and meets head of humerus dissection, increase containing and the compressing of steel plate to sclerite or pulverizing bone piece, screw and steel plate are angled fixing, increase anti-vertical withdrawal force, steel plate design becomes only to fix trochiterian size, be conducive to Micro-operation, solved sclerite pulverizing and can not make the problem being screwed.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that performing creative labour can make or distortion still within protection scope of the present invention.
